stripe, imitates a dead leaf stalk. Their attitudes 
are stiff and motionless, and it is astonishing how 
easily the searching eye passes them over though 
they are comparatively large caterpillars. When 
one is found the appearance should be carefully 
noted that the eye may be trained to detect another 
and not be again deceived, for though not so 
common as the leaf-rollers one of these pests will 
soon destroy a bud. 
The larve of a good many other moths occasion- 
ally feed on Rose plants, and in certain districts 
some may become locally special pests. The cater- 
pillar of the gold-tailed moth (Auriflua), sometimes 
called the palmer worm, I have found occasionally 
devouring Rose leaves. This is a beautiful and 
highly coloured caterpillar, with bright tufts of 
hair; it feeds on the leaves of many sorts of trees, 
but I have most commonly found it on the hawthorn. 
The saw-flies (Tenthredinide) are so called from 
the shape and nature of their ovipositors, the instru- 
ments with which the females pierce the leaves or 
bark for the insertion of their eggs. There are 
several genera and species which feed on Rose 
plants, but I have found it impossible, with these as 
with the moths, to name them all. I was told by the 
late Rev. J. H. Hocking, who most kindly assisted 
me in the identification of insects, that there would 
be no room for Roses in my book if I were to 
attempt it. In my grounds there are two special 
saw-flies (Selandria), very distinct in habit, and 
perhaps including more than two species, which are 
particularly troublesome. 
The presence of the first may be known by the 
singular appearance of the lower and older leaves
